' Claims.

This invention relates to an electric vaporizer of the class set forth in my Patent No. 1,628,784, May 17, 1927, except as to certain modifications in the construction of the heater and mounting I for the terminal plug, and also in the construction of the cap or cover for the receptacle.

The main object of the present invention is to permanently associate the terminal plug with the receptacle in such manner that it may be 10. moved rectilinearly into and out of engagement with terminals of the heater and also moved laterally or transversely to and from a position above the top or cover of the receptacle.

Another object is to arrange the electrodes in II. the liquid to be vaporized in such manner that the liquid may have free passage vertically from theunderside upwardly and return to assure cleansing of the adjacent sides of the electrodes from foreign mattenand to prevent accumulation of such foreign matter between the electrodes which might otherwise short circuit the same.

A further object isto provide the cover with a vapordischarge nozzle of insulating material 25 to further increase the safety of the device against short circuits, and also to prevent contact of the user with any of the energized conductors of the heater circuit.

Other objects and uses relating to specific parts 7 10 or the vaporizer will be brought out in the following description.

In the drawing: Figure 1 is a perspective view ofan electric vaporizer embodying. the various features of my,

ll .invention. I

Figure-2 isan enlarged longitudinal sectional view of the same device taken in the plane of line 2-2, Figure 1, the dotted lines indicating the rectilinear adjustment of the terminal plug and its supporting means.

Figure 3 is a side elevation partly in section of the upper portion of the vaporizer in which the supporting bail forfthe plug is swung laterally and downwardly from its normal operative to position.

As illustrated, the receptacle 1 for the liquid to be vaporized is loosely seated at its lower end upon a supporting base 2 preferably of sheet metal spun or otherwise molded to the desired form with its lower end face disposed in a substantially horizontal plane to rest upon a table or other support, and its upper end provided with an annular flange 3 surrounding the lower end of the receptacle.

68- The frame also comprises a pair of similar arms 4 having theirlower ends passed apertures 5 in the base 2' and secured by 'rivets' 6 to the inner sides of said base at diametrically opposite sides thereof, and their upper ends extended vertically some distance abovethe upper ends of the base and along corresponding sides of the receptacle 1 in spaced relation thereto for receiving and supporting an annular band or ring 7 and the lower ends of a vertically and lat-v, erally movable plug-supporting member or ball 8.

The band 7 is secured by rivets 9 or equivalent fastening means to the intermediate portions of the arms 4 and extends around the periphery .of the receptacle 1 to assist in holding the latter in an upright position upon the base 2. A pair of pivotal studs or pins 10 are riveted or otherwise secured to the upper'ends of the arms 4 4 to form limiting stops and pivots for the adjacent ends of the bail 8. This ball 8 is provided with opposite arms 11 extending downwardly 78 along diametrically opposite sides of the receptacle 1 and along the upper-ends of the arms 4 so as to overlap on said arms'in vertically sliding engagement therewith, the arms 11 being provided with-vertically elongated slots 12 through which so f the corresponding pivotal pins or studs 10 are adapted to project: to permit said sliding movement. I

These slots 12 are closed at their lower and upper ends and are somewhat longer than the engaging portions of the plug with the heater ter minals to permit rectilinear movement of the plug parallel with the axis of the receptacle into and out of engagement with the heater terminals.

The lower walls of the slots cooperate with the 00 studs 10' to limit the verticalmovement of 'the plug out of engagement with the heater terminals, and also serve as pivotal connections between the amis 11' and arms 4 to allow the lateral swinging movement of the bail with the plug 96 thereon when the; plug is disengaged from the heater terminals, thus permitting the removal of the receptacle from the frame and the cover from the receptacle. 4

The receptacle 1 is provided with a removable cover 13 consisting of a disk 14 of insulating material and a peripheral band. 15 of sheet metal which is tightly but releasably fitted upon the periphery of. the section 14 and is provided with apendent threaded flange 16 adapted to screw end of the receptacle 1.

The insulating section 14 when closed rests upon the upper end of the receptacle 1 to form a l qu d and. vapor tight joint therewith and is prol10 upon a corresponding externally threaded upper vided with a vertically inclined discharge nozzle 17 extending from one side of the axis laterally and diametrically some distance to the opposite side of the axis'for directing the vapor from the interior of the receptacle to the exterior thereof as may be required. 7 I q The discharge opening in the insulated section 14 is tapered from its inner end to its outer end to permit the free flow of the vapor therethrough and to discharge it in the form of a relatively small jet with sufficient force to carry the vapor a considerable distance beyond the outlet of the nozzle which is preferably arranged in a plane at right angles to the bail-B and midway between ,the electrode conductors of the heater presently described.-

A hanger section A of insulating material is secured at its upper end to the underside of the central portion of the cover section 14'to extend downwardly therefrom into the receptacle 1 and within a relatively short distance from the bottom thereof for receiving and supporting a pair of electrodes l8 and conducting rods 19 of the electric heater.

7 That is, the electric heater comprises, in this instance, a pair of similar rectangular cubes 18 of carbon or equivalent conducting material seated at their upper ends against the lower end of the insulating hanger A in transversely spaced relation to form an intervening water gap 20 which is closed at the top but open at'the bottom and at opposite sides to permit free circulation of the liquid from the bottom upwardly between and against the adjacent sides of the electrodes for cleansing the same by the liquid flux, and also to prevent lodgment of any foreign matter between the electrodes which might tend to short circuit the same.

The conducting rods 19 are extended through parallel vertical openings 21 in the hanger section latter against the 10" 2r end face of the section A.

The lower end of the section A is provided with a central transverse rib is extending a relatively short distance downwardly between the upper ends of the electrodes 18 to hold the latter in parallel spaced relation against turning movement I when securing them in place by the tightening of that when energized by the closing of the heater rods 19.

The upper ends of the conducting rods 19 are throughregistering openings24inthe insulating section 14 of the cover at opposite sides of the vapor discharge opening 1'1 and are threadedtoreceiveinternallythreadedterminals25 of the heater circuit. These terminals 25 are seated attheir lower ends in suitable in the upper side of the section 14 to extend upwardly somedistanceabovethecover andareelectrically connected to the electrodeslil through the medi,- um ofthe conducting rods 19.

The terminal plug previously mentioned is mounted upon the ball 8 to move'therewithinto and out of engagement with the terminals 25 and -comprisesloweranduppersections26 andz'l of .rowinaplaneatrightanglestotheplaneofthe terminals or of nightly greater horizontaldepth than'said terminals.

Th insulatggsection'dli is steed to and between the adjacent portions of the arms 11 of the bail 8 by screws 32 'or equivalent fastening means. The upper portion of the bail extends some distance above and diametrically across the top of the plug in spaced relation thereto to form a handle by which the entire apparatus may be carried from place vto place in an upright position.

The lower ends of the arms 11 of the bail are spring-pressed toward each other and against the adjacent arms .4, and are provided with outwardly pressed 'portions 33 adapted to ride over and upon the outer rounded ends of the pivots 9 to frictionally hold the bail and plug in their down positions, or rather to establish a frictional lock between the bail and supporting frame for the receptacle 1, and thereby to facilitate the carrying of the receptacle by means of the bail 8 when desired. V

The plug terminals 31 are provided with binding posts 34 to which are connected suitable lead and return wires 35 of the heater circuit.

The supporting frame. for the receptacle, in-

eluding the base 2, arms 4 and "band or ring '7,

constitutes a connection between the bail and receptacle, while the bail forms a support for the terminal plug for moving said plug into and out of engagement with the terminals of the heater, and also to and from a position across the cover of the receptacle.

It is evident from the foregoing description and the-accompanying drawing that when the terminal plug is in operative engagement with the terminals 25 of the heater, it would not be possible to remove the cover fromthe receptacle nor the receptacle from the frame while the plug is in engagement with said terminals.

In other words, the .cover 13 constitutes a removable lid for the receptacle 1, while the electric heater comprising the electrodes 18 and conductors 19 are suspended from said lid and are provided with outwardly projecting terminals 25 for engagement with an electric plug.

The supporting frame for the receptacle and the bail 8 constitutes means engaging said receptacle and said plug to prevent the removal of said lid while the plug is in engagement withv said terminals.

The electrodes of the heater are adapted to be submerged in the contents of the receptacle so gap 20 will be heated and its heat transferred to the remaining portions of the liquid to vaporize the same and allow the vapor to escape through the discharge nozzle 17.'

The construction shown and described is particularly compact and eflicient in expeditiously converting the liquid into vapor but-it is obvious that various changes might be made in thedetail construction without departing from the spirit of this'invention.

The purpose in preventing the removal of the no cover 14. while the electric plug is in engagement with the terminals 25 of the heater, is to prevent contact of the user with any of the live conductors of the heater circuit and heater when the cover with the heater thereon is removed from the receptacle.

. For example, when 'the electric plug is-removed from theheater terminals the circuit to the heater willbebroken while the terminals 31 of sa d circuit will be enclosed and concealed 1m thereof will be exposed to'contact withthe ment with said terminals.

the plug with and from within the insulating block 26 so thatno parts hands of the user.

It is also evident that, when the electric plug is removed from the heater terminals, the current to the heater will also be cut of! so that by swinging the ball 8 carrying the electric plug laterally from a position over the cover 14 to a position at one side thereof the cover with the heater thereon may be readily unscrewed or removed from the receptacle 1, at which time the electrodes 18 and conductors 19 and terminals 25 of the heater will be disconnected'from the heater circuit and may be safely cleansed or adjusted without danger to the user.

It is now clear that as long as the electric plug 26 is engaged with the terminals 25, as shown in Figure 1, it will be impossible to turn or remove the cover 13 and heating unit from the receptacle, or to turn or remove the receptacle from its supporting frame by reason of the fact that the plug is secured to the ball 8 and that the bail is pivoted to the frame members 4 which, in turn, are secured to the base member 2, thus preventing exposure of the heater to handling until the plug is removed from the terminals 25.

On the other hand, when the bail 8 with the plug thereon is drawn upwardly for disengaging the plug from the terminals 25-to the polinesinFigure 2, the.

sition shown by dotted I heater circuit will be broken and the bail and plug may thenbe rocked laterally about the pivots 10 to one side of the cover, as shown in Figure 3, thus permitting the removal of the cover with the heater thereon and also permitting the removal of the bottlefrom the frame by upward'displacement, if desired, under which conditions the heating element may be handled or cleansed without liability of injury to the user from the heating circuit.
